This wl_display proxy is temporary only until waylandsink goes NULL,
at which point the connection to the display is disposed. Unfortunately,
if this is advertised as a GstContext, playbin will cache it and re-feed
it to the sink when it goes PLAYING again, but the wl_display pointer
will at that point be invalid and cause a crash.
Another solution to the problem would be to also cache the GstWlDisplay
object inside the GstContext, which would automatically ref-count
the display connection, but I see no reason in doing that at the moment,
as there are no known users of this GstContext outside waylandsink.
It's probably better to avoid chasing hidden refcounts.

If a (master) playlist contains a variant list entry without a
URI then during parsing of the next variant list entry we are
a) leaking the entry we're currently parsing (new_list), and
b) free'ing the pointer to the previous list entry (list) without
updating the pointer.
Hence when then adding the URI for the latest parsed entry, incorrect
information is stored, as the information is used from 'list' which
is not valid memory anymore, also leading to crashes.
Fix this by correctly storing the new variant list entry pointer
as needed.

Nicer to read, two lines of code less, and also the callback
function should've been a GCompareFunc that returns a gint
and not a boolean (it did work correctly, was just confusing).
Currently float and int are supported by default. vec2, vec3, vec4
and mat4 are supported if graphene is used. Of course if one wants
to set custom uniforms they can also be set using the create-shader
signal.
We know that the gchar arrays contain at least one string. Furthermore,
g_strfreev() checks if the array is NULL and simply returns if it is.
Hence, there is no need to check if the array is empty before using
g_strfreev().

In order to ensure the sequence_position will always be consistently updated,
store the current file duration.
This way, when we advance, we can always increment the position based on what
was previously outputted.

One may not have an GstGLContext available or current in the thread where one
would need to update the shader. Support this by signalling create-shader
whenever the one-shot 'update-shader' is set to TRUE.
A GstGLShader is now simply a collection of stages that are
compiled and linked together into a program. The uniform/attribute
interface has remained the same.
Allows playlists that are missing the mediasequence information to
be correctly parsed. If the playlist was updated without reseting
the mediasequence it would constantly increase over subsequent updates,
leading to issues during playback.
For live streams, we want to make sure there's a certain distance
between the sequence to play and the last (earliest) fragment.
The problem is that it assumes there are at least 3 fragments in
the playlist, which might not always be the case (like in the case
of a server restarting and gradually adding fragments).
In order to avoid ending up with negative sequence numbers (which
will just loop forever), limit the new target sequence number to
the highest of:
* either the first sequence number of the playlist (fallback)
* or 3 fragments from the last one (standard behaviour)
Change the gstcvdilate.c file extension to cpp and add it into Makefile for
consistency with other elements of opencv and because Opencv not support C
language in new API 2.4.11.

Change the gstretinex.c file to cpp and add it into Makefile.
It is necessary to migrate the retinex element to C++,
because new Opencv API leaves obsolete functions like cvSmooth.
This element uses this function.
You can see in this link:

int smoothtype, int size1, int size2, double sigma1, double sigma2)

The cascade classifier changes its structure on new version of OpenCV 2.4.11.
It is need to migrate to C++ to utilize the new load method of OpenCV which
allows to load the old and new classifiers.

This is mostly a copy/paste of the negotiation function in
basetextoverlay, which was improved recently to handle many more cases.
This will allow us to negotiate a window size with downstream.

Doing the contrary has no effect and the consequence is that playback
will start with the lowest bitrate even if we can already handle
higher bitrate.

Not doing this can lead the demuxer to attempt downloading fragments
for an invalid start time. The server would then send a HTTP
Precondition failed error, the demuxer would try some more times to
download the invalid fragment and eventually error out.

Move the TAG defines directly into the code, not sure what
their purposes is, these are printf format strings so having
them directly as literals in the code where they're used
makes the code easier to follow.
Remove playlist_str GString variable from GstM3U8Playlist struct,
since it's only used temporarily in playlist_render(). Might just
as well keep it local then.
Transform is set to be done in place in gstcvdilateerode.c, so the in-place
transform function is always used and the other is redundant. Removing it.

When running GStreamer from uninstalled sources, the location of the haar
cascade files will be local. Check if running in uninstalled and set the
file paths accordingly.
Move handling of a GstSample in a separate function, and unref the
sample after calling it. libass copies the font data so we don't need to
keep it around.
